Sorry this is so late in answering but due to the hurricane have been busy with family.

To answer which keys to use if you can already see the blue dots that are the trajectory handles here they are

Hold down T key and click and drag on the blue dot to change tension(sharpnees of curve)
Hold down C key and click and drag on blue dot to change continuity (sharpness of curve too)
Hold down B key and click and drag on blue dot to change bias

On a path with at least 3 points you can use the alt key and click and drag to twist the path.
